Rev. 2 — 2 February 2024
Product data sheet
1. General description
The NXS0506GU-Q100 is an SD 3.0-compatible bidirectional dual supply level translator with
auto-direction control. It is designed to interface between a memory card operating at 1.7 V
to 3.6 V signal levels and a host with a nominal supply voltage of 1.1 V to 1.95 V. The device
supports SD 3.0: SDR104, SDR50, DDR50, SDR25, SDR12 and SD 2.0 High-Speed (50 MHz)
and Default-Speed (25 MHz) modes. The device has a built-in EMI filter and robust ESD protection
(IEC 61000-4-2, level 4).
This product has been qualified to the Automotive Electronics Council (AEC) standard Q100
(Grade 2) and is suitable for use in automotive applications.
